We successfully achieved a two way DNC connection between a PC and a PO LY GIM – PLG 42 lathe that is controlled by a Mitsubishi Meldas 60/60s controller so as to directly send/receive G-code to/from the controller.

We were asked to program the productive manufacturing of three precision parts. The manufacturing procedure was done utilising a 3-axis CNC machine tool and the final result can be seen to the following picture.

We managed to check and measure the backlash of a 3-axis FADAL 3016 so as to change the relevant parameters of the controller and finally compensate the positioning error of the axes.

After the measurement of the backlash error of the axes and the correction of the relevant parameters, the positioning error eliminated to the minimum possible given the analysis of the machine tool (~0.0025μm ή ~0.0001in).
